Hello,

hi my name is antwonn and 1 day i restart my computer to install some windows 7 updates and they r required and i was afraid if i didnt install i would get B.S.O.D Like i did on Windows Vista And Xp (Dual Boot) so once i shutdown my computer i leave it off like 4 10-30 seconds cause i had 2 use the bathroom so once i come back 2 turn my computer on it does the regular HP screen then shows black screen with a gray _ blinking (on my computer its normal) then after it says
